OpenStudy (anonymous):

OpenStudy (zarkon):

x>7 x<1

OpenStudy (anonymous):

okayy thanks :)

OpenStudy (saifoo.khan):

i was in a doubt too, Zarkon.. plz tell me where i went wrong!

OpenStudy (saifoo.khan):

x-4 > 3 or x-4 < 3 x > 7 or X < 7

OpenStudy (zarkon):

|x-4|>3 ==> (x-4)>3 -(x-4)>3 solve both

OpenStudy (saifoo.khan):

x-4 > 3 or x-4 < -3 x > 7 or X < 1

OpenStudy (saifoo.khan):

OpenStudy (zarkon):
